摘要
介绍了基于声卡的信号采集系统,对声卡采集过程中,采样频率、采样长度、采样位数、通道数等参数的设置及相应控制程序的实现等问题进行阐述,系统软件用VC++编写,可实时显示信号波形,进行信号分析处理,还可将信号直接存储为数据文件.
This paper introduces the signal collecting system based on sound card. It resolves some problems about parameters setting of sampling frequency、sampling length、sample bits、chunnel numbers etc and reality of corresponding control procedure during signal sampling. system software is programmed by VC++. It can realize the functions of signal waveform display, signal analysis and processing, and savt it in form of data files.
